: Use ratio language to describe the relationship of any two things you can think of. Example: For every 5 minutes of jogging, I ran 500 yards. Be creative and come up with your own idea.
Answers
For every 5 minutes of jogging, I ran 500 yards
To Find : Use ratio language to describe the relationship of any two things
Determine the unit rate
Solution:
every 5 minutes of jogging, I ran 500 yards
=> 500/5 = 100 yards/ minute
For every 20 minutes , I can type 1000 words in
unit rate = 1000/20 = 50 words per minute
For every 1 hr (60 minutes) I can solve 10 Questions
unit rate = 10/60 = 1/6 Question per minute
For every 10 minutes , i can read 5 pages
unit rate = 5/10 = 1/2 pages per minute

Noah drove 480km in 5 hours. About how far did he drive in 2 hours?
Answers
Answer:
192km
Step-by-step explanation:
480/5 = x/2
5x = 960
/5 /5
x = 192
Answer:
If Noah's driving was at a constant rate, he drove 192 km in 2 hours
Step-by-step explanation:
In order to find the answer to this question then we can set up two equations with x meaning the km/h he is going and y as our answer.
Noah drove 480km in 5 hours can be set up as:
480 = 5x
Dividing both side by 5:
x=96
and we want to find the number of km he drove in 2 hours:
y = 2 x
because we know x=96 from the first equation
y = 196 so, therefore, Noah drove 192 km in 2 hours
x = 16 - 4y
3x + 4y =8
substitution method
Answers
Answer:
i think x = -4, y = 5
Step-by-step explanation:
x = 16 - 4y
3x + 4y = 8
3(16 - 4y)+4y = 8
48-12y+4y = 8
48-8y = 8
48-8 = 8y
40 = 8y
5 = y
so
x = 16 - 4y
x = 16 - 4(5)
x = 16 - 20
x = -4

Find the slope of the line segment shown.
A) -1/2
B -1
C 1/3
D 1
Answers
Answer:
D)
Step-by-step explanation:
The answer would be D. The slope of a line is how fast it climbs. Height divided by base. Up divided by over. Thus, if it goes across 3 and up 1, its slope would be 1/3. If it goes across 1 and up 2, the slope is 2. If it goes across 1 and up -1, the slope is -1.

A fabric paint manufacturing company fills the paint in containers using a machine. The amount of paint in a container follows a normal distribution with a mean of 99 ml and a standard deviation of 5 ml. What is the probability that the quantity of paint filled is less than 100 ml? A) 0.28 B) 0.42 C) 0.58 D) 0.92
Answers
Answer:
The correct answer is C) 0.58
Step-by-step explanation:
All this is from USATESTPREP:
The function normCdf(x0, x1, , ) gives the probability that a value drawn from a normal distribution with mean and standard deviation lies in the interval [x0, x1].As the normal distribution is symmetric, the probability that a value is less than the mean is exactly 0.5P(x ≤ 100) = P(x < 99) + P(99 ≤ x ≤ 100)= 0.5 + normCdf(99,100,99,5) = 0.5793Rounded to the nearest hundredth, the probability that a container is filed with less than 100 ml is 0.58.

A linear function is expressed by a graph of a line that
crosses both axes at the origin. An equation is written in
slope-intercept form to express the same function as
shown in the graph. From just this information, what
statements can be made?
The slope of the equation must be positive.
The y-intercept of the equation is zero.
It is possible that the line on the graph is horizontal.
The slope of the equation must be negative.
Answers
Answer:
The y-intercept must be zero.
It is possible that the line is horizontal.
Step-by-step explanation:
The description states that the line "crosses both axes at the origin." That would mean that the point (0,0) is on the graph. The y-intercept is the value of y when x=0. We see that it is zero in this case (0,0).
The description says nothing about the slope. So it could be either positive or negative. But it could also mean that the slope is zero. A zero slope would be a horizontal line. So that is a second statement that is true: "It is possible that the line on the graph is horizontal."

Step-by-step explanation:

A pattern can either follow an arithmetic sequence, a geometric sequence or a user defined sequence.
The term that completes the sequence is (d) 9:49
The sequence is given as:
8:07, 8:58, ?, 10:43, 11:37
The above sequence follows an arithmetic sequence, and the common difference (d) is calculated using:
d = 8:58 - 8:07
This gives
d = 51 seconds
The missing term (which is the third term) is then calculated using:
T3 = 8:58 + 51 seconds
This gives
T3 = 9:49
Hence, the term that completes the sequence is (d) 9:49
